5 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 5, Fixed firefighting systems using water. This second edition cancels and replaces the first edition (ISO :1993), which has been technically revised. ISO 6182 consists of the following parts, under the general title Fire protection Automatic sprinkler systems: Part 1: Requirements and test methods for sprinklers Part 2: Requirements and test methods for wet alarm valves, retard chambers and water motor alarms Part 3: Requirements and test methods for dry pipe valves Part 4: Requirements and test methods for quick-opening devices Part 5: Requirements and test methods for deluge valves Part 7: Requirements and test methods for early suppression fast response (ESFR) sprinklers Part 9: Requirements and test methods for water mist nozzles Part 10: Requirements and test methods for domestic sprinklers Part 11: Requirements and test methods for pipe hangers ISO 2004 All rights reserved v

7 INTERNATIONAL STANDARD ISO :2004(E) Fire protection Automatic sprinkler systems Part 1: Requirements and test methods for sprinklers 1 Scope This part of ISO 6182 specifies performance and marking requirements and test methods for conventional, spray, flat spray and sidewall sprinklers. It is not applicable to sprinklers having multiple orifices. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 7-1:1982, Pipe threads where pressure-tight joints are made on the threads Part 1: Dimensions, tolerances and designation ISO 49, Malleable cast iron fittings threaded to ISO 7-1 ISO 65, Carbon steel tubes suitable for screwing in accordance with ISO 7-1 PPP-B-640D:1969, Federal Specification for Boxes, Fiberboard, Corrugated, Triple-wall 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 General sprinkler thermosensitive device designed to react at a predetermined temperature by automatically releasing a stream of water and distributing it in a specified pattern and quantity over a designated area conductivity factor C measure of the conductance between the sprinkler's heat-responsive element and the fitting NOTE The conductivity factor is expressed in units of (m/s) 0,5. ISO 2004 All rights reserved 1

8 3.1.3 response time index RTI measure of sprinkler sensitivity where RTI = t u t u is equal to the time constant, expressed in seconds, of the heat-responsive element; is the gas velocity, expressed in metres per second NOTE 1 The response time index is expressed in units of (m s) 0,5. NOTE 2 RTI can be used in combination with the conductivity factor (C) to predict the response of a sprinkler in fire environments defined in terms of gas temperature and velocity versus time standard orientation orientation that produces the shortest response time with the axis of the sprinkler inlet perpendicular to the air flow NOTE In the case of symmetrical heat-responsive elements, standard orientation is with the air flow perpendicular to both the axis of the waterway and the plane of the frame arms; in the case of non-symmetrical heat-responsive elements, it is with the air flow perpendicular to both the waterway axis and the plane of the frame arms which produces the shortest response time worst-case orientation response orientation that produces the longest response time with the axis of the sprinkler inlet perpendicular to the air flow assembly load force exerted on the sprinkler body at 0 MPa (0 bar) hydraulic pressure at the inlet design load force exerted on the release element at the service load of the sprinkler service load combined force exerted on the sprinkler body by the assembly load of the sprinkler and the equivalent force of a 1,2 MPa (12 bar) hydraulic pressure of the inlet average design strength axial glass bulb supplier's specified and assured lowest average design strength of any batch of 50 bulbs 3.2 Types of sprinkler according to type of heat-responsive element fusible element sprinkler sprinkler that opens under the influence of heat by the melting of a component glass bulb sprinkler sprinkler that opens under the influence of heat by the bursting of the glass bulb through pressure resulting from expansion of the fluid enclosed therein 2 ISO 2004 All rights reserved
